To all wlwm it com-em:

Be 1t known that 1, WILLIAM GRAY, a citizen of the United States, andresident of Lincoln, in the county of Lancaster and State of Nebraska,have invented an Improved Feed for Grain, Ore, and Mineral Separaters,of which the following is a specification. My nventlon consists incertain novel constructlons and combinations of parts as hereis a sideelevationand section of a separator provided with myimprovement; Fig. 2is a cross section on llne 22 of Fig. 1; and Fig.

3 is a perspective view of the curved chute,

and the grains or particles composing such materials were heldto acertain degree in close contact, and in consequence the current of airforced upward through the vertical spout or chamber failed to act on thematerials in the most eflective manner. I have found that by deliveringthe materials in a horizontal plane or directly across the verticalspout and therefore atright angles to the ascending air current, theyare spread out in a thinner sheet so that the air current acts thereonmore effectively, or in other words, forces u ward and separates thelighter materials' om the heavier in a more perfect manner than ispracticable when the materials are discharged in a downward direction.

carryin out my invention, I have provided the inc ed spout at itsjunction with the vertical spout outside of the latter with a curvedplate or chute A, as indicated in Fig. 1. The form of the late or chuteis more plainly indicated in Fig. '3, the u per portion thereof having aflange a which projects downward, and the lower end a/ being curvedupward to 8,, slight degree. The

flange a is ada ted to enter a slot or socket 1) formed on t e lowerside of the spout- B which connects with the vertical spout C.

The spout D from the hopper E enters the aforesald spout B and overla sthe upper edge of the plate or chute A. e spout D thus serves as a meansfor holdin the plate A in place, although its own gravltyand the fric-Bpecification of Letters Patent. bgpliwtion-fllol October as, 1906.- muKm 340,123..

tion of its flange a with the socket b ma ordinarily suffice for thisurpose. It be seen that the grain 01' ot er material assing from thehopper E through the spout is deflected by the curved lower enda of thechute, so as to, discharge into the vertical s out C in a horizontaldirection or diametrica y across the said spout. In other words,'the ainor other material is discharged in a p ane at rightangles to thedirection of the ascending air current received from the fan F, and thegranular or other material composing the material just delivered intothe spout C are spread out in a thin sheet and adapted to be acted uponby. the air current in such manner entirely uno structed, and

allows a full, free, or unhindered air current therein.

When the plate or chute O is worn out or when it is desired tosubstitute another having a different curvature as may be required bydifferent qualities and conditions of grain or other material to beseparated, the substitution may be quickly and easily effected by simplyraising the hopper, to ether with its s out D, and then lifting the its'ange a is drawn out of t e socket b. The latter may be formed by adownward bend in the-spout" B or in any other referred manner, or byconstructingl it in a se arate iece and attaching it to t at 7 claimisate so that e spout.

air blast spout and the inclined grain s out connected with one side ofthe same, 0 the feed plate arranged wholly within said grain spout atits junction with the air spout and curved at its outer end to ahorizontal plane and its free edge terminating flush, or in verticalalinement, with the adjacent vertical sideof the air spout, as shown anddescribed.

2. In a separator of the class indicated, the combination with avertical air spout and an inclined spout connected therewith, andprovided with a socket in its lower side, of a chute comprising a platehaving its lower end curved and its upper ortion formed withaflan cadated to entert e said socket, substantia ly as escribed.

3. In a separatorof the class indicated, the combination with a verticalspout and an inclined spout having a socket in the lower side, of a feedplate which is curved at its lower end and provided at-its upper endwith a flange adapted to enter said socket,

and a hopper spout entering the said in- 10 chned spout and overlappintheu per edgeof the feed plate, substantiafi as d escribed.
